To aZZ w/wm it may concern.-

Be it known that I, ALBERT A. BoYnR, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a new and useful Improvement in Machines forCleaning Carpets, of which the following is a specification.

My invention consists of a machine for cleaning carpets which has anadjustable vertical frame carrying a pad for holding the carpet, saidframe being heldin its adjusted position on the housings or standingframe by a pair of pawls that engage with toothed racks, in combinationwith a revolving shaft in front of said pad, carrying beater-straps,whereby a carpet when laid 011 the pad may be advanced to or recededfrom said beaters, in accommo- I dation to the force of the blowsdesired to be struck.

The invention also consists in the combination of said carpet-carryingframe with another frame at the lower part of the machine that slidesbetween the housings and guidestrips, said carpet-carrying frame beingconnected therewith by an upright post at each side, the two framesbeing so connected that when the lower one is moved inward or outward anangle of any desired degree may be given to the pad holding the carpet,to suit fabrics of different textures.

In the accompanying drawings, which make a part of this specification,Figure 1 is avertical section at the line a m of Fig. 2. Fig. 2 is aplan view of the machine. Fig. 3 is an end elevation of the adjustablebed-frame B and parts attached. Fig. 4. is a face view of abeater-stock, G, and connected parts on an enlarged scale. Fig. 5 is anedge view of the same. Fig. 6 is afacc view of the beater-stock- Galone.

Like letters of reference in all the figures indicate the same parts.

A represents the standing frame of the machine with which the severalparts are con nected.

B is an adjustable vertical frame provided with the bed or pad 0, onwhich the carpet D (seen in Fig. 1) is beaten as it is drawn forward inthe direction of the arrow.

E is a revolving shaft with which the beat- (No model.)

ers are connected, having on one end a pulley, F, which is connected bymeans of a belt with the motive power. The shaft is provided with aseries of beater-stocks, G, connected therewith by means of thepivot-bolts a and eyebolts b b,- and H are beater-straps, made ofrubber, and connected to the stocks G at one end by means of thethumb-screw pins 0 and openings 0, whereby to provide for an expeditiousdetachment of Worn-out straps for the connection of new ones, theattachment being easily made by passing the end of a strap andconnecting the slot with the head-pin, or the detachment made byremoving the strap from the pin and then drawing it through the openlngc.

The beaters are arranged in spiral form, as represented in Fig. 2, toprovide for the blows being given continuously, in regular succession.There are gum-straps I, which are arranged on an angle, as shown in Fig.1, which hold the carpet above the pad 0 until forced down by the blowsof the boaters successively, (the upper end being connected to the bar(I, and the lower end to the board 6, which board supports the pad orbed 0,) thereby giving a springing movement to the oarpet,to assist inloosening the dirt.

The frame B is adjustable inward and outward by means of its connectionwith the horizontal sliding frame B, which rests upon the bottom board,f, of the stationary frame A, being guided by the uprights of the saidframe and the guide-strips g g. The lower end of the frame B is seatedin bearings of the frame B, and anangular position is given to it bymoving the latter frame in or out, to give any required angle to the bedor pad 0, the frame being confined in its adjusted position by means ofpins h h, which enter suitable holes in the. board f,- and the saidframe B is adjusted at its upper end also by means of the pairs of pawlsi 2' and racks J J, it being moved inward or outward, as may berequired, to'vary the distance of the pad 0 from the beater-shaft G, inorder to vary the length of the blows of the beaters; and hence, by theadjustment of the frame B at its lower end, it may be so arranged as tocause flat blows on heavy carpets and angular blows 011 light carpets,and by the adjustment of its upper end to cause the carpets to receiveany desired 3.
